Abstract

a invenção tem como objeto um recinto de mancal (e) de uma turbomáquina que compreende uma parede fixa (9), uma árvore giratória (5), uma primeira e uma segunda juntas de estanqueidade (10, 20) entre a parede e a árvore, e uma câmara (cam) entre a parede fixa (9) e um elemento de estator (19) alimentada com ar por uma abertura (19a) próxima da dita árvore (5). o recinto é caracterizado pelo fato de que um meio (30) de guia de ar é disposto ao longo da superfície da parede (9) do recinto, exterior a esse último, de modo que pelo menos uma parte do ar que sai do meio de guia passe através da primeira junta de estanqueidade (10) e a árvore, esse meio de guia sendo alimentado com ar por uma captação de ar distante radialmente da árvore, o ar proveniente da captação de ar estando a uma pressão mais elevada do que ao nível da árvore (5).
